1 HUMIDIIPIER AND :DUs'r coLLEcToR.

p Application led `.lJecemher This invention relates to neW and useful improvements in humidifiers and `dust col? lectors for dwellings,V and particularly when used With registers in hot air heating sys# tcms. n y

The objects of the invention are to provide ahumidiiier which can be readily'jat tached to the register and which is `so constructedthat it occupies very little space and is adjustable for use in connection with registers of various constructions'.

Further objects ofthe invention are to provide humidifiers and dust collectors which are neat in appearance,V can `be easily cleaned and refilled with clean Water and are provided With means for inducing vthe air to circulate therethrough, therebylcausing the hot air to heat the watercontained therein and mix with the moisture produced by the evaporation of Water so that the air o't the 'room in `which ythe humidifier is lon cated'is maintainedkat the 'properdegree of humidity and is kept free oi dust which is separated from the air and deposited in said humidifier. lfVith these and other objects in view, my invention consists incertain novel features of construction and arrangement of "parts, hereinafter more fully described and claimerh and illustrated in the accompanying drawings, in `whicl y Figure 1 is front elevational View ci a humidifier attached to a register. y

Figure 2 is a plan' View of the same. Figure is an enlarged end elevational View `with a portion of the register shown in section. 1

Figure 4 is an enlarged vertical cross scction taken on line 4 4 of Figure 1.`

Figure 5v is a section taken on line 55-5 ot Figure 3.` n "y Figure@ isa lcross 6260i Figure.v y i 4 y n y Referring by numerals to the accompanying drawings,;10 indicates a Wall register ota hotair heating system and arranged above said register is an open topcasing 11 which is approximately ot' the saine length section taken on line .as the register and is comparatively narrow in Width soV as to occupy very little space when in position. The rear Wall 12 of the casing is disposedlvertically and is adapted to be placed against the wall of the room.k

Ilfhe front Wall 13 of the casing is inclined .trom vertical so as to overhang the register.' 1() and is provided with a plurality of openings 14 through which the air discharged by the register is admitted into Vthe casing also serve to permit admission of air within the casing.

A container or pan 18 is arranged within casing 11 and rests on a paid oi asbestos or otherabsorbent material 19. This pad acts as a cushion for a container' 18 and absorbsv the moisture formed inthe casing by con- .dcnsation or otherwise introduced therein.

Container of smiillerdimensions than the casing ll'lso that it is spaced `from the front and end Walls ot the casing a suitable distance to permit air admitted into the casing to come in contact with the Walls of said container, thereby heating the Water contained therein and producing evaporation thereof.

vThe upper' end of casing 11 is closed by atop 20 having downwardly presented marginal lianges 21 which fit against the edges of casing ll and serve to hold said cover in placer This cover is provided with a series of openings 22 through which the air is dis charged from the casing 1l. Container 1.8 terminates a suitable distance below the top of casing 11 in order to provide a mixing chamberjwherein the air-.and the vaporare mixed before being discharged from the casing. Container 18 is provided with suitable hand holes 18 by means of which the container can be readily removed from the casing. f

Inaddition to deector plates 15, an apron or extension 24 may be used to deflect the air discharged by the register toward the casing, it so'desired;` This extension isl hinged at 25 to a hook 26s() that said extension may be folded upwardly out of the Way as shovvnin dottedlinesj in Figure 3. A

hook 26 is provided on each side of extension 24 and is` detachably Vseated .in a seat or socket 2T `formed in the wall 13 of casing 1l.

(so i `which are adapted to be secured to the vgrille or grating 10 of register 10. `At

taching means 28 comprises a U-shape member 29, the parallel portions 30Y of which are slotted and are adjustably secured to vertically dispoed bars 31 which are attached to the end walls 16 of casing 11 and extend a suitable distance below the same. Slotted portions 30 are attached to bars 31 by means of thumb screws 32 lwhereby member 29 may be shifted in a vert-ical plane relative to casing 11 and can be disposed at an angle to bars 3l with thumb screws 32 being. used as pivots.

Ushaped clips 34 remov-'ablyengage the horizontal iortion 29l of member 29 and have depending legs 35 which are adapted to be placed against the outer sidev of grille 10. A screw 36 is carried by each member 35 and screw-seated in a member 37 which is removably disposed on the opposite side of grille 10a so that by tightening screw 3G a portion of grille 10All is clamped between members 35 and 37, thereby securing member 29 rigidly in position. The vertical ad justment ot' member 29 permits disposition of clamping members 35 and 37 at a suit able point on the grille of the register andV the angular adjustment of member 29 enables the attaching of member 29 to registers having their gratings or grilles disposed at various angles.

Bars 31 may be slotted vertically and the slotted portions of members 30 may be bent at right angles to provide for wider range of adjustments. Thumb screws 32 engage nuts 38, and lock washers 39 may be used to hold the parts against displacement. bottom ot' container 18 isv preferably made to fit snugly within the casing 11 andthe walls of the container are arranged angularly to the corresponding walls of the-container in order to provide air space between the respective walls` and allowecirculation of air therebetween. Container 18 may be removed forcleaning purposes and relled with fresh water. Similarly, casing 11 can be detached from supporting means by unscrewing thumb screws 32 whereuponv said casing can be cleaned and if necessary pad 19 replaced by a new one. Casing 11 and top or cover 20 can be made in any desired finish so as to harmonize with the register and can be ot' any suitable design or shape.

My improved humidifier is simple in construction, can be easily cleaned and supplies the air with the propell amount of moisture necessary to maintain the rooms in healtbful condition. y
